This high-power RGB LED from Adafruit delivers serious brightness, with each red, green, and blue die capable of handling 350–750mA continuous current (2A peak). At 3W it produces approximately 150 lumens, scaling up to around 300 lumens at the full 9W.
The LED comes pre-mounted on an aluminium PCB that serves as both a mounting base and partial heatsink. This is a common-anode configuration, so all three colour channels share a single positive connection.
Key Features
- High Power Output – 3W to 9W operation with up to ~300 lumens
- Full RGB Colour Mixing – Independent red, green, and blue dies for millions of colours
- Common Anode – Shared positive connection for all three channels
- Aluminium PCB Mount – Pre-mounted on a metal-core PCB for heat dissipation
- High Current Capacity – 350–750mA continuous per channel, 2A peak
Specifications
- Power – 3W (at ~350mA/channel) to 9W (at ~750mA/channel)
- Luminous Output – ~150 lumens at 3W, ~300 lumens at 9W
- Configuration – Common anode
- Current per Channel – 350–750mA continuous, 2A peak
- Mounting – Aluminium PCB
Ideal For
- High-brightness RGB lighting projects
- Stage and effects lighting
- Colour-mixing experiments
- Custom lamp and fixture builds

- 1× 3W–9W RGB LED on aluminium PCB
Jargon buster
Plain-language definitions for the technical terms used above.
- common-anode
- A wiring arrangement where several LEDs or LED segments share a common positive (anode) terminal and are switched individually on their negative (cathode) side. Common-anode and common-cathode parts, such as RGB LEDs, seven-segment displays, matrices and strips, are not interchangeable without a suitable driver.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
